  2. 64-bit computing - Wikipedia

    en.wikipedia.org/wiki/64-bit_computing

    A 64-bit word can be expressed as a sequence of 16 hexadecimal digits. In computer architecture, 64-bit integers, memory addresses, or other data units [a] are those that are 64 bits wide. Also, 64-bit central processing units (CPU) and arithmetic logic units (ALU) are those that are based on processor registers, address buses, or data buses of ...

  9. 128-bit computing - Wikipedia

    en.wikipedia.org/wiki/128-bit_computing

    Since the VAX's registers were 32 bits wide, a 128-bit operation used four consecutive registers or four longwords in memory. The ICL 2900 Series provided a 128-bit accumulator, and its instruction set included 128-bit floating-point and packed decimal arithmetic. A CPU with 128-bit multimedia extensions was designed by researchers in 1999.
